RE: Legal shooting time???
As a retired state conservation officer, I can report that this is not nit picked too much from an enforcement standpoint. For instance, here in Colorado, the legal hours vary one minute for every 12 miles east or west of Denver. Then there are watches that run a little slow or fast. Main deal is that you can positively identify that the animal is legal, see your sights,and make a safe shot. This could vary a few minutes either way depending on conditions.
